I first drew my schematic with one GND wire name and convert it to PCB. I have now to split the GND wire with two different wire GNDP and GNDN. I corrected my schematic. After i update My PCB i find the new tracks with the right nets name in the design manager but the old track is still here with GND net name. How do i split the old GND Track with the two new nets name without having to do a new layout and delete the old net Thanks
